NOTE:
LDFQ1:LDFQ0 — PWM Load Frequency Bits
When reading these bits, the value read is the buffer value (not
necessarily the value the PWM generator is currently using).
IPOL1 — Top/Bottom Correction Bit for PWM Pair 1 (PWMs 1 and 2)
When reading this bit, the value read is the buffer value (not necessarily
the value the output control block is currently using).
IPOL2 — Top/Bottom Correction Bit for PWM Pair 2 (PWMs 3 and 4)
When reading this bit, the value read is the buffer value (not necessarily
the value the output control block is currently using).
IPOL3 — Top/Bottom Correction Bit for PWM Pair 3 (PWMs 5 and 6)

These buffered read/write bits select the PWM CPU load frequency
according to
This buffered read/write bit selects which PWM value register is used
if top/bottom correction is to be achieved without current sensing.
